Can't launch Apple Remote Desktop anymore

If I remove or rename /var/folders/zz than I fail to reboot.

Could this issue be related to corrupted disk or some other hardware issue ?

But DiskUtil tells me my disk is OK

My ordeal started after I did a restore from Time Machine a few days ago.

Now ARD fails to start.

I also use Carbon Copy backup to clone my main volume once a day and has never seen this before.

Does Apple ever read these forums ?

Eventually we should only have emptied the /var/folders/zz folder and not removed or renamed. I did the same as you.

Interesting to know that even a Apple's Time Machine didn't work here either.

There is another thread that deals with the same issue because a CCC restore doesn't help here either: https://discussions.apple.com/thread/7618604?answerId=30473108022#30473108022

I was getting the same error in Console

3/22/16 10:16:36.035 AM ARDAgent[6057]: libcoreservices: _dirhelper: 400: mkdir: path=/var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/C/ modes[2]=0700: Permission denied

But I decided to go a more conservative route. I noticed that on my other machines that directory had different permissions. I logged enabled root and logged in as root in terminal. Then I set the permissions on that directory to match those on the machine ARD is working on.

chmod 751 /var/folders/zz/zyxvpxvq6csfxvn_n0000000000000

So far that is working for me.

Aren't those folders SIP protected ?

For me the issue happened after a disk crash and a restore from Time Machine.

I'm sure TM is bug free and I am doing smth stupid. Yea right.

But in the end I chose to go with a clean ElCap image.

Running 10.10.5 and recently started getting the Remote Desktop error as others here have experienced.

Tried reinstalling Remote Desktop 3.8 from App store.... did not fix error

Tried removing /var/folders/zz as suggested... did not fix error

Tried reinstalling ARD Agent (Download Apple Remote Desktop 3.8.5.1 Client)... did not fix error

What did work for me:

Delete Remote Desktop application

Delete System/Library/CoreServices/RemoteManagement/

-then

Reinstall Remote Desktop 3.8 from App Store

Reinstall Remote Desktop Client 3.8.5.1

Although I lost all of the saved logins to all 84 machines, ARD successfully launched and asked to reset the Admin Password.

✅ Working as expected now.

Deleting the zz folder sometimes foxes the problem, yet sometimes I have to completely remove ARD and redownload and re-setup. This keeps happening and its really irritating. Any permanent solution?

Another, possibly simpler, technique also worked. I booted off another volume and from there I was able to use the Finder to get to the zz folder and trash it.

To use the Finder instead of Terminal, I used 'Go To Folder..." under the Go menu and input '/Volumes/myOtherBootableDisk/var/folders/' to get to the enclosing folder. Next, I dragged the zz folder to the trash and emptied it. However, one of the folders inside of zz had permissions that wouldn't allow me to delete it. So, I did a 'Get Info' on it and gave everyone read and write and then I was able to Empty Trash completely.

Thanks so much to those that spoke up about this problem and offered suggestions. I had it on both of my machines after upgrading the hard disk and it was killing my productivity to lose ARD.

U Make my day mate. :-) Working! Have reinstall my MaxOSX 10.11.6 from a usb stick via carbon copy cloner to my macPro. After this, the ARD crash wirh the same problem. Ur idea help me.

TIP! U don't need the SIP via Recovery Terminal...

Activate ur Root user with password for the Terminal. Make su and ur idea will work too. :-)

Cheers,

X.
